Analyzing Overconstrained Design of Compliant Mechanisms

Volume 4: 8th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A and B, 2011
Whereas the use of compliant mechanisms is favorable for high precision applications, the constraints must be dealt with carefully. In an overconstrained design the actual natural frequencies and stiffnesses can differ considerably from their intended values.

Compliant Mechanisms for Robotic Ankles

Volume 6A: 37th Mechanisms and Robotics Conference, 2013
We have developed a compliant robotic tendon mechanism for a robotic ankle. In this paper, we analyze the differences between a stiff and compliant robotic tendon versus a stiff and compliant slider crank mechanism. The compliant, slider-crank mechanism reduces peak forces and speed required by an actuator at the ankle.

Auxetic structure design using compliant mechanisms: A topology optimization approach with polygonal finite elements

Advances in Engineering Software, 2019
Compliant mechanisms are monolithic structures where the movement is given by the flexibility of the structure rather than the presence of joints and pins. The absence of joints allows the construction of compliant mechanisms in microscale. In this work,

Modeling Large Deflections of Initially Curved Beams in Compliant Mechanisms Using Chained Beam Constraint Model

Journal of Mechanisms and Robotics, 2018
Understanding and analyzing large and nonlinear deflections are the major challenges of designing compliant mechanisms. Initially, curved beams can offer potential advantages to designers of compliant mechanisms and provide useful alternatives to ...

Compliant transmission mechanisms

2018
Classical human-engineered transmission mechanisms such as linkages, gears, and couplings are well established designs which made out of multiple parts and rigid hinges. However, these mechanisms impose disadvantages such as wear, friction, low precision and reliability, need for assembly and lubrications, and difficulty for miniaturization.

Magneto-Elastic Compliant Mechanisms

Volume 6C: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract The motivation for this work has been a variety of motions like navigation of pipelines, insertion operations in assembly, and gripping actions, which require the adaptation of the mechanism to the external constraints, rather than avoid them.

Origami-inspired sacrificial joints for folding compliant mechanisms

Mechanism and Machine Theory, 2019
Folding is a manufacturing method which can create complex 3D geometries from flat materials and can be particularly useful in cost-sensitive or planar-limited fabrication applications.

Active Compliant Parallel Mechanisms

Volume 5A: 38th Mechanisms and Robotics Conference, 2014
In a novel compliant parallel mechanism, a motor and spring are arranged in a parallel fashion and are connected to a movable lever arm. The motor pushes and pulls on one attachment point and the spring stores and releases energy at a second attachment point.

A nonprobabilistic reliability–based topology optimization method of compliant mechanisms with interval uncertainties

International Journal for Numerical Methods in Engineering, 2019
On account of the inevitable multisource uncertainty factors in compliant mechanisms, which seriously affect the accuracy of output motion, a nonprobabilistic reliability–based topology optimization (NRBTO) framework for compliant mechanisms with ...

Mechanisms of Compliant Shells

2019
Thin shells are three dimensional curved solids with a thickness that is small compared to the two other dimensions. For structural engineers, traditional rigid thin shells are some of the most efficient structural typologies. The curvature and continuity that characterizes them are the source of their high stiffness under loading.
